Answer:

20

Step-by-step explanation:

the comment below or above me has everything right except one thing. 4 plus 2 plus 3 equals 9, Not 10. 180 divided by 9 equals 20 and there's your answer

All the interior angles of a triangle always add up to 180 degrees.

3x + (2x + 20) + (4x - 20) = 180
3x + 2x + 20 + 4x - 20 = 180
3x + 2x + 4x + 20 - 20 = 180
10x = 180
x = 180/10
Therefore, x = 18

A motorcycle is traveling at a constant speed of 45 miles per hour. how many feet does it travel in 6 seconds? remember that 1 m
Fantom [35]

Answer:

The total number of feet travelled by the motorcycle is 396 feet

Step-by-step explanation:

Using the constant speed relationship with the distance:

           v = s/t

From the above equation the distance travelled will be:

          s = v * t              (i)

We are given with the v, that is:

          v = 45 miles per hour

Converting in to feet per second.

          v = (45 * 5280)/3600 feet / s

          v = 66 feet per second

Now, put that v and t in equation (i)

          s = 66 * 6

          s = 396 feet

Given A is between Y and Z YA = 5.5, AZ = 2x, and YZ = 41.5 =, find AZ
morpeh [17]
YZ = YA + AZ
41.5 = 5.5 + AZ
AZ = 41.5 - 5.5
AZ = 36

So, your final answer is AZ = 36

Hope this helps!
